Cząsteczki z przestrzeni – Gaz pierwotny

Cząsteczki z przestrzeni – Gaz pierwotny – Has been confirmed the hypothesis about the origin of molecules from space. The researchers were able to discover the so-called. Primary gas, which was created shortly after the Big Bang, it consists of hydrogen and its heavier isotope deuterium. This finding confirms that in the Big Bang were created only the lightest chemical elements, hydrogen and helium. Heavier elements appeared only after 100 million years.

Mierzenie kształtu, wielkości asteroid

Mierzenie kształtu, wielkości asteroid – French scientists from the Observatoire de la Cote d’Azur have developed a new way of measuring the shape and size of asteroids. They used an interferometer constructed of 2 VLT telescopes, with diameters of 8.2 m. To measure the asteroid Barbara. The results indicate that the asteroid is composed of two parts with a diameter of 37 and 21 km. Apart from each other 24 km.

Najchłodniejsze miejsce układu słonecznego – American space probe Lunar Reconnaissance Orbiter (LRO), close to the pole of the Moon, on the southwestern edge of the crater Hermite discovered the coldest place of the solar system. The temperature was -249 ° C, thus lacking 24 ° C to the point of absolute zero. Substance cooled to -273.15 ° C, or to absolute zero, has no thermal energy. It is a place which does not escape any direct sunlight.

Sonda kosmiczna Galileo na Jowiszu – In October, 1989. Space shuttle Atlantis took into space probe Galileo. Did not move out of orbit straight to Jupiter, but first flew in the direction of Venus, which was used to assist gravity. In the same order twice used the Earth and finally moved toward the gas giant. Along the way, the first probe approached asteroid, specifically Gaspra, a distance of 1600 km.

Galileo probe to Jupiter was heard after 7 years and accompanied him the next 8. It became his artificial satellite. Among other things, sent into the atmosphere of Jupiter measuring instrument, which in hellish conditions lasted almost an hour. Several times flew near the Galilean moons: Io, Ganymede, Europa and Callisto. Discovered that beneath the surface of the last three is salty ocean water.

Due to the good operation of the systems, the probe mission was extended several times (the last time at the end of April 2001.). Made a total of 34 laps around Jupiter. At that time, 7 times visited Io, Callisto 8 times, as many times Ganymede, 11 times Europe.

Wiatr słoneczny – Słońce ma wpływ na procesy zachodzące w Układzie Słonecznym na wiele różnych sposobów. Although gravity is maintained thanks to its system time emits a space wide range of molecular types of radiation, to which the feature ” wind of the Sun”. Researchers from the University of Leicester have combined the data. Obtained during the observations of solar activity from data obtained during observations of the Martian atmosphere, provided by satellites. The solar corona disappears from the environment until 2.5 x more particles. Observations were conducted during the fall of solar activity within the 11 – year solar cycle.

Sonda kosmiczna Deep Impact – NASA space probe named Deep Impact during the flight within 700 km of comet Hartley 2, was attacked pieces of ice about the size of a basketball. The researchers had never observed such a phenomenon. The reason for this situation was likely to influence the evaporation of solid carbon dioxide.

Kometa Hartley 2

Kometa Hartley 2 – Which is indeed one of the smallest comet, it is the source of many remarkable discoveries. The researchers found that releases more gases than other similar to the comet. When approached to Earth in September 2010. With its nucleus in 8 days released up a huge amount of double cyanide produced by the toxic cyanides. Comet Hartley 2 is much smaller than the other, but much more active.

Utrata pozycji Plutona – At the General Assembly of the International Astronomical Union in Prague in 2006. It was decided that Pluto is not a planet. On the ballot passed the definition of a planet. Pursuant to the findings of a celestial body being a contender for this name must circulate orbit. Its mass and gravity to be so large that formed the shape of a round. In addition, there should be other large bodies in their neighborhood.
